The new deal is part of a major award from Transport for London. It is an eight-year agreement, apportioned to three suppliers that will see the capital’s 6,000 traffic signals upgraded and maintained to the latest, greenest standards.

The contract for Telent Technology Services is believed to be the largest single traffic signal supply and maintenance contract ever awarded in the UK.

With operations throughout London and the rest of the UK, Telent will supply, install and maintain all traffic control equipment in the west and south west of London, making it responsible for 49 per cent of London’s traffic signal estate.

Telent will help expand the use of intelligent traffic signals, as well as new crossings for pedestrians and cyclists - all helping to deliver benefits to road users. Chris Metcalfe, managing director of technology solutions at Telent, said: “Winning this contract is a tremendous moment for telent and builds on our growing capability and reputation for world class levels of commitment, support and know-how.

“It positions us as a key technology services supplier to TfL’s Surface Transport Directorate in what is undoubtedly a flagship contract anywhere within the Urban Traffic Industry.

“fIt is also a great acknowledgement for our people – who have tremendous pride and dedication in what they do – their individual efforts and track record have all contributed to making this possible.”

Transport for London said that the contracts were part of a doubling of the investment into London’s road network – from £2billion to £4billion – and the contracts would deliver a saving of around £42million compared to other contracts.

Dana Skelley, director of asset management at TfL, said: “London is world-leading when it comes to traffic signals management and our new contracts will allow us to remain at the cutting edge of traffic control technology.

“We have a range of works planned to improve traffic signals across London and we look forward to working hard with our partners to implement them.”

This is the latest success for Telent, which recently announced it had won three five-year contracts worth over £15million with the Highways Agency, to maintain roadside technology across the east, south East and M25 regions’ motorways and trunk roads.
